Management of Moderate-to-Severe Atopic Dermatitis in Adults: A Cross-Sectional Survey of Dermatologists Within the Asia–Pacific Region
Introduction Limited evidence is available on real-world management of atopic dermatitis (AD) among Asian adults. This cross-sectional study aimed to assess current approaches in AD diagnosis and management in Asia. Methods Practising dermatologists regularly treating patients with moderate-to-severe AD were recruited from eight Asia–Pacific territories, namely Mainland China, Hong Kong, India, Japan, Singapore, South Korea, Taiwan, and Thailand. A survey was administered to eligible dermatologists after screening and taking informed consent. Data from fully completed submissions were analysed using descriptive statistics. The study was reviewed by the institutional review board in each territory. Results Data from 271 dermatologists were included for analysis. About one-third (31.7%) reported that they referred to the Hanifin and Rajka criteria during diagnosis. The majority of dermatologists used clinical impression when assessing AD severity and treatment response. Reduction of eczema and pruritus was the primary treatment objective when managing both acute (98.1%) and chronic (69.1%) AD. More than half of dermatologists preferred adding systemic anti-inflammatory medication for patients who did not respond to maximized topical treatment, while 43.6% would switch to another systemic medication for those failing to respond to maximized systemic treatment. Topical corticosteroids were frequently selected by dermatologists. For systemic therapies, oral corticosteroids were most frequently used, followed by cyclosporin and dupilumab. Narrow-band ultraviolet B was the most common phototherapy reported (84.9%). There was considerable variation in estimated average and maximum durations of therapies used to treat AD. Conclusion This study has provided insights on the real-world management of moderate-to-severe AD in the Asia–Pacific region. The diverse approaches in diagnosis and treatment highlight the multifactorial nature of AD, reliance on clinical judgement, and importance of personalized care. To improve outcomes in patients with AD, it will be crucial to develop biomarkers for diagnosis, reduce subjectivity in assessment, as well as promote access to newer and effective therapies.

Quality of Life and Burden of Moderate-to-Severe Atopic Dermatitis in Adult Patients Within the Asia–Pacific Region: A Cross-sectional Survey
Introduction The burden of atopic dermatitis (AD) is significant, with a substantial impact on quality of life (QoL). This cross-sectional study aimed to ascertain the burden of AD, its impact on QoL, and associated costs. Methods Patients with moderate-to-severe AD were enrolled from eight territories, namely Hong Kong, India, Japan, Mainland China, Singapore, South Korea, Taiwan, and Thailand. After screening was performed and informed consent was obtained, eligible participants were asked to provide responses on their AD symptoms, severity, treatment, and out-of-pocket costs via an online survey. QoL was assessed using EQ-5D-5L and Dermatology Life Quality Index (DLQI), while productivity loss was quantified using the Work Productivity and Activity Impairment (WPAI) questionnaire. Data from completed submissions were analyzed using descriptive statistics. The study was reviewed by the institutional review board in each territory. Results Median age of enrolled patients (N = 1103) was 41.0 years (interquartile range, IQR 16.0). The majority of patients reported that their head/neck, trunk, upper limbs, and lower limbs were affected during a flare. Topical (74.2%) and oral steroids (58.7%) were frequently prescribed to manage AD. Common atopic comorbidities were allergic urticaria (64.2%), allergic rhinitis (61.8%), and allergic conjunctivitis (51.5%). Median DLQI score was 13.0 (IQR 11.0), while median EQ-5D-5L (based on China value set) score was 0.8 (IQR 0.4); 87.2% and 77.2% of patients reported pain/discomfort and anxiety/depression on the EQ-5D-5L domains, respectively. Median total annual costs associated with AD were USD 10,128.52 (IQR 12,963.26) per patient, with indirect costs being the largest component. Findings from WPAI indicated that presenteeism is a major contributor to productivity loss. Conclusion This multinational survey study showed that AD is associated with substantial QoL impairment and economic burden among Asian adult patients with moderate-to-severe AD. To alleviate burden of AD, clinicians should be more proactive in managing other concomitant conditions including psychological issues, and advocate for increased reimbursement for AD treatments.

Rationale, Design, and Baseline Characteristics of Participants in the Health@NUS mHealth Augmented Cohort Study Examining Student-to-Work Life Transition: Protocol for a Prospective Cohort Study
Background: Integration of mobile health data collection methods into cohort studies enables the collection of intensive longitudinal information, which gives deeper insights into individuals’ health and lifestyle behavioral patterns over time, as compared to traditional cohort methods with less frequent data collection. These findings can then fill the gaps that remain in understanding how various lifestyle behaviors interact as students graduate from university and seek employment (student-to-work life transition), where the inability to adapt quickly to a changing environment greatly affects the mental well-being of young adults. Objective: This paper aims to provide an overview of the study methodology and baseline characteristics of participants in Health@NUS, a longitudinal study leveraging mobile health to examine the trajectories of health behaviors, physical health, and well-being, and their diverse determinants, for young adults during the student-to-work life transition. Methods: University students were recruited between August 2020 and June 2022 in Singapore. Participants would complete biometric assessments and questionnaires at 3 time points (baseline, 12-, and 24-month follow-up visits) and use a Fitbit smartwatch and smartphone app to continuously collect physical activity, sedentary behavior, sleep, and dietary data over the 2 years. Additionally, up to 12 two-week-long bursts of app-based ecological momentary surveys capturing lifestyle behaviors and well-being would be sent out among the 3 time points. Results: Interested participants (n=1556) were screened for eligibility, and 776 participants were enrolled in the study between August 2020 and June 2022. Participants were mostly female (441/776, 56.8%), of Chinese ethnicity (741/776, 92%), undergraduate students (759/776, 97.8%), and had a mean BMI of 21.9 (SD 3.3) kg/m2, and a mean age of 22.7 (SD 1.7) years. A substantial proportion were overweight (202/776, 26.1%) or obese (42/776, 5.4%), had indicated poor mental well-being (World Health Organization-5 Well-Being Index ≤50; 291/776, 37.7%), or were at higher risk for psychological distress (Kessler Psychological Distress Scale ≥13; 109/776, 14.1%). Conclusions: The findings from this study will provide detailed insights into the determinants and trajectories of health behaviors, health, and well-being during the student-to-work life transition experienced by young adults.

Bridging the Gap: Comparing Patient-Clinician Views on Treatment Goals and Communication in the Management of Atopic Dermatitis Within the Asia–Pacific Region
Introduction It remains unclear how patients with atopic dermatitis (AD) and clinicians perceive the level of patient–clinician communication and if there could be potential lapses. This cross-sectional study aims to compare perspectives between patients with AD and dermatologists regarding communication and treatment expectations in Asia. Methods Moderate-to-severe patients with AD and practicing dermatologists were recruited from eight Asia–Pacific territories, including Mainland China, Hong Kong, India, Japan, Singapore, South Korea, Taiwan, and Thailand. Patients and dermatologists completed separate surveys designed to elicit their expectations regarding AD management, and their perceived level of patient–clinician communication. Patients were also asked about their treatment satisfaction and whether they prefer additional treatment beyond what was prescribed. Demographic information and responses were analyzed using descriptive statistics. The study was reviewed by the institutional review board in each territory, and all participants provided informed consent. Results A total of 1103 patients and 271 dermatologists completed the surveys. Both patients and dermatologists were largely aligned in their top treatment goals in AD management. However, greater proportions of patients prioritized the prevention of exacerbation (78.0% versus 47.2%), minimization of treatment adverse effects (46.4% versus 9.1%), and improvement in mental health (16.0% versus 4.9%), compared with dermatologists. Although patient–clinician communication was observed to be generally good, 10.9% of patients reported dissatisfaction with communication in AD management. The majority of patients were either “very satisfied” or “satisfied” with their latest acute AD treatment, but 65.5% of patients still desired additional treatment. Conclusions This multinational study has provided insights on the perspectives of Asian patients and dermatologists in treatment goals, AD management, and communication. In general, both patients and dermatologists were aligned in treatment goals and there was satisfactory patient–clinician communication in most aspects. However, potential areas of improvement have been identified to further enhance patient-centered care.

Correlates of sedentary behavior in Asian preschool‐aged children: A systematic review
Summary: This systematic review aims to identify the multilevel correlates of sedentary behavior (SB) and its sub‐domains among preschool‐aged children aged 0–7 years in Asia. We systematically searched for studies published from 2000 onwards using terms related to SB correlates and Asia in six databases. Eligible studies were observational and used quantitative methods to examine correlates of total, and domain‐specific SB (screen viewing [SV] and non‐screen‐based SB) in Asian children living in Asia. Two reviewers independently screened identified references. Following quality assessment of included studies, we performed narrative synthesis to summarize the evidence on the intrapersonal, interpersonal, environmental correlates of total and domain‐specific SB (PROSPERO: CRD42018095268). Twenty‐two studies from 4 regions and 12 countries/territories were included. Out of the 94 correlates explored, the following associations were consistent: older age, being a boy, non‐Chinese ethnicity (Southeast Asia), younger maternal age, higher maternal and paternal television‐viewing time with higher SV; higher SV at earlier age with higher SV and total SB; and presence of TV/computer in the bedroom with higher leisure‐time SB. We encourage more studies from low‐ and middle‐income Asian countries with an increased focus on different SB domains, further exploration of environmental correlates, and the use of objective measurements to capture SB.

Understanding physical activity and sedentary behaviour among preschool-aged children in Singapore: a mixed-methods approach
Objectives This study investigated physical activity (PA) and sedentary behaviour (SB) among preschool-aged children in Singapore and potential correlates at multiple levels of the socioecological model from in-school and out-of-school settings. Design A cross-sectional study using a mixed-methods approach. Participants Parent–child dyads from six preschools in Singapore. Methods PA and SB of children (n=72) were quantified using wrist-worn accelerometers for seven consecutive days. Three focus group discussions (FGDs) among 12 teachers explored diverse influences on children’s activities, and System for Observing Play and Leisure Activity in Youth (SOPLAY) assessed PA environment and children’s activity levels at preschools. Seventy-three parents completed questionnaires on home and neighbourhood factors influencing children’s PA and SB. Descriptive analyses of quantitative data and thematic analysis of FGDs were performed. Results Based on accelerometry, children (4.4±1.1 years) spent a median of 7.8 (IQR 6.4–9.0) hours/day in SB, and 0.5 (0.3–0.8) hours/day in moderate-to-vigorous physical activity (MVPA). MVPA was similar throughout the week, and SB was slightly higher on non-school days. In preschools, SOPLAY showed more children engaging in MVPA outdoors (34.0%) than indoors (7.7%), and absence of portable active play equipment. FGDs revealed issues that could restrict active time at preschool, including academic requirements of the central curriculum and its local implementation. The teachers had varying knowledge about PA guidelines and perceived that the children were sufficiently active. In out-of-school settings, parents reported that their children rarely used outdoor facilities for active play and spent little time in active travel. Few children (23.5%) participated in extracurricular sports, but most (94.5%) reported watching screens for 1.5 (0.5–3.0) hours/day. Conclusion MVPA was low and SB was high in preschool-aged children in an urban Asian setting. We identified diverse in-school and out-of-school correlates of PA and SB that should be taken into account in health promotion strategies.

Results Based on accelerometry, children (4.4±1.1 years) spent a median of 7.8 (IQR 6.4–9.0) hours/day in SB, and 0.5 (0.3–0.8) hours/day in moderate-to-vigorous physical activity (MVPA). MVPA was similar throughout the week, and SB was slightly higher on non-school days. In preschools, SOPLAY showed more children engaging in MVPA outdoors (34.0%) than indoors (7.7%), and absence of portable active play equipment. FGDs revealed issues that could restrict active time at preschool, including academic requirements of the central curriculum and its local implementation. The teachers had varying knowledge about PA guidelines and perceived that the children were sufficiently active. In out-of-school settings, parents reported that their children rarely used outdoor facilities for active play and spent little time in active travel. Few children (23.5%) participated in extracurricular sports, but most (94.5%) reported watching screens for 1.5 (0.5–3.0) hours/day. Conclusion MVPA was low and SB was high in preschool-aged children in an urban Asian setting. We identified diverse in-school and out-of-school correlates of PA and SB that should be taken into account in health promotion strategies.

Correlates of sedentary behaviour in Asian adults: A systematic review
Summary: The objective of this study is to systematically review the evidence on correlates of sedentary behaviour (SB) among Asian adults. We searched for studies that examined individual, environmental, and political/cultural correlates of total and domain‐specific SB (transport, occupation, leisure, and screen time) in Asian adults published from 2000 onwards in nine scientific databases. Two reviewers independently screened identified references. Following quality assessment of included studies, we performed narrative synthesis that considered differences based on SB measurements, regions, and population characteristics (PROSPERO: CRD42018095268). We identified 13 249 papers of which we included 49, from four regions and 12 countries. Researchers conducted cross‐sectional analyses and most relied on SB self‐report for SB measurement. Of the 118 correlates studied, the following associations were consistent: higher age, living in an urban area (East Asia), and lower mental health with higher total SB; higher education with higher total and occupational SB; higher income with higher leisure‐time SB; higher transit density with higher total SB in older East Asians; and being an unmarried women with higher SB in the Middle East. We encourage more research in non‐high‐income countries across regions, further exploration of important but neglected correlates using longitudinal designs and qualitative research, and the use of objective instruments to collect SB data.
